Chainlink Introduces Offline Computing Tools and Bridging – Bits Media

Chainlink Developers Announce Decentralized Off-Grid Computing Tools Chainlink Keepers, as well as interconnect "bridges" with risk monitoring to protect against fraud.

Chainlink decentralized oracle network developers have announced the launch of new tools during the annual SmartCon event. Keepers – this is a kind of service level, which tells smart contracts, how to behave in different situations.

New feature available on Ethereum and supported by Aave protocols, Synthetix, PoolTogether, Barnbridge, Bancor и Alchemix. Chainlink Labs also announced the launch of bridges between blockchains, which contain a risk monitoring component to protect against fraud.

The next step in the development of the project, according to Chainlink White Paper 2.0
- adding calculations, as well as data inputs via the same decentralized network. Chainlink co-founder Sergey Nazarov explained, what is meant by computation.

"A smart contract cannot know, What time is it now", – said Nazarov. “He has no concept of time. If you want to, so that the smart contract is concluded exactly at midnight on Tuesday, you need Keeper ".

A common form of computing, used in DeFi applications, could be launching limit orders or monitoring certain debt pools for under-collateralized loans. Design teams are now building this computational layer in-house.. But this goes against the whole concept of decentralization., said Nazarov.

“We have created a full cycle decentralized application. It has decentralization of code and decentralization of all systems., controlling the code. because, if the code is partially decentralized, attacks using “quick loans” and other attacks in the DeFi industry ", – Nazarov notes.

According to him, Keepers will be selected from a pool of trusted host operators, and their profit will ensure that computations are performed at any level of congestion or in any cost scenario. More corporate-level operators will join the network in the future, eg, T-Systems and Deutsche Telekom.

According to Chainlink roadmap, the last two years the team has been working on the Cross-Chain Interoperability Protocol (CCIP). Chainlink also announced a Programmable Token Bridge, which will be built on top of CCIP. The "bridge" can be used to send tokens and computational commands to any blockchain, which opens up the possibility of running more advanced internetworking applications.

Cryptocurrency lending platform Celsius announced its intention to use CCIP. "The time has come for this", – said Nazarov, citing vulnerabilities
in THORChain.

"Developers face two fundamental challenges in bridging design.", – said Nazarov. “They either create an insufficiently secure system, or they have no relationship with other blockchains, which will provide support for the bridge ".

According to Nazarov, CCIP Chainlink uses something like a multi-signature security system, which is designed this way, to aggregate signatures from hundreds of trusted Chainlink nodes. Besides, the new anti-fraud network will run in parallel with the Chainlink bridging and track every signature, data transmission, adding or removing a node. Nazarov added, that this network has the ability to block the bridge at any time unilaterally.

"This creates an important level of risk management and anti-fraud.", – said Nazarov. “If you look at any system in the world, which moves the value, then they all have anti-fraud and risk departments. They invest a lot of money in fraud protection systems. But for some reason, we want to move billions of dollars across all these bridges without a risk management system.. What's the point of this?».

In the spring it became known, what Chainlink developers create
new off-grid decentralized oracles, which can provide solutions for both scalability of supported networks, and for other problems. Recently, the Avalanche blockchain developers added
support of Chainlink decentralized oracles for the development of the ecosystem of DeFi projects on the network.
